Gather a colander full of lemons off your tree. Pick some rosemary on your way back inside. Peel the lemons and blanch a few of their peels. Chop up the flesh of the rest, no seeds please. Put lemon flesh in pot with some sugar and bring to simmer. Cut off the pith of the peels you blanched and slice into thin strips, add to pot with a bit of water. Cook down and add rosemary at the end. Hot jar can and dream of all the ways you'll use it (on ice cream!)
